Abstract: In this talk I will consider the problem of explicitly computing the graded perverse sheaf associated to the weight filtration on the sheaf of nearby cycles for some Shimura varieties with Iwahori level structure. Using an explicit formula for the semi-simple trace of Frobenius on nearby cycles (earlier joint work with B.C. Ngo) together with Gaitsgory's observation that inertia acts purely unipotently on the nearby cycles, one can give an algorithm to compute the graded pieces in the...

Speaker : Hosam Mahmoud Keywords : Analysis of algorithms; Poly urn; stochastic process embedding; Poissonization; Leonard pair. Abstract : We take a view of Urn models that abandons the picking of balls from an urn and considers embedded versions into a Poisson process. A connection to partial differential equations is discussed and exact and asympotic solutions are presented for diagonal cases.

Speaker : Conrado Martinez Keywords: Analysis of algorithms; partial sorting; quicksort; quickselect; divide and conquer recurrences. Abstract: In this lecture I present a preliminary analysis of partial quicksort, a simple variant of quicksort which efficiently solves the partial sort problem. I also present similar results for chunksort, another generalization of quicksort which can be used to sort designated intervals of an array.
